Log Management

On the System Log tab page, perform the following steps to view system runtime logs.

• System logs cannot be deleted in the MindStudio GUI. To manage logs, perform the following operations:
  • RC scenario: Log in to the device as the root user and manage logs in the /var/log/npu/slog directory.
  • EP scenario: Log in to the system as the SSH user and manage logs in the $HOME/ascend/log/ directory.
• Before viewing system logs, you need to add a device.
• For a Windows server that has a chip installed, the log flush path is C:\Program Files\Huawei\Ascend\alog\device-{device-id}. You need to log in to the server to manage logs.

1. In the Log window in MindStudio, click the System Log tab page. In the device list, click a device to expand the log list of the device.
